From the Sector

Geosynthetics have become an indispensable part of the construction industry. PP nonwovens, for example - mechanically bonded continuous fibres made from specially UV-stabilised polypropylenes - are often used in blanket form as barriers, screens and filters, and their strength extends the service life of construction projects. Whether for road construction, or as barrier on glaciers or against weeds - there are myriad applications.

TenCate Geosynthetics uses the PURE LOOP ISEC evo technology to recycle this type of PP nonwoven. The European company, with locations in Austria, France and the Netherlands, is specialised in the development and production of geotextiles for modern civil engineering applications. The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

"The demands on us were high," recalls Patrick Wiesinger, project manager at PURE LOOP. "The PP nonwoven is highly tear resistant, which means its a very challenging recycling process. Our ISEC evo machine conserves the quality of the production waste really well during recycling, so we were able to achieve the specified increase in quality for the recyclates."

Another advantage of PURE LOOP technology is the wide range of shapes in which the production scrap can be delivered for processing. "Our ifeed technology with double feed ram system and singleshaft shredder offers the ideal conditions for direct processing of these large rolls - and without the need for prior preparation of the input material by employees before the material is fed into the recycling process", emphasizes Patrick Wiesinger. With the ISEC evo recycling machine TenCate can now manufacture its high-strength PP nonwoven product with a recyclate content of up to 10 percent.

• An innovative European project to process and recycle plastic textile waste
• A partnership to reach the objectives set by the European Union in reducing CO2 emissions by 2030
• A unique consortium rallying 16 public and private European organizations working together for more circular economy

Carbios joined WhiteCycle, a project coordinated by Michelin, which was launched in July 2022. Its main goal is to develop a circular solution to convert complex^[1] waste containing textile made of plastic into products with high added value. Co-funded by Horizon Europe, the European Union’s research and innovation program, this unprecedented public/private European partnership includes 16 organizations and will run for four years.
 
WhiteCycle envisions that by 2030 the uptake and deployment of its circular solution will lead to the annual recycling of more than 2 million tons of the third most widely used plastic in the world, PET^[2]. This project should prevent landfilling or incineration of more than 1.8 million tons of that plastic each year. Also, it should enable reduction of CO2 emissions by around 2 million tons.
 
Complex waste containing textile (PET) from end-of-life tyres, hoses and multilayer clothes are currently difficult to recycle, but could soon become recyclable thanks to the project outcomes. Raw material from PET plastic waste could go back into creation of high-performance products, through a circular and viable value chain.
 
Public and private European organizations are combining their scientific and industrial expertises:

• industrial partners (Michelin, Mandals, KORDSA);
• cross-sector partnership (Inditex)
• waste management companies (Synergies TLC, ESTATO);
• intelligent monitoring systems for sorting (IRIS);
• biological recycling SME (Carbios);
• product life cycle analysis company (IPOINT);
• university, expert in FAIR data management (HVL);
• universities, research and technology organizations (PPRIME – Université de Poitiers/CNRS, DITF, IFTH, ERASME);
• industry cluster (Axelera);
• project management consulting company (Dynergie).

 
The consortium will develop new processes required throughout the industrial value chain:

• Innovative sorting technologies, to enable significant increase of the PET plastic content of complex waste streams in order to better process them;
• A pre-treatment for recuperated PET plastic content, followed by a breakthrough recycling enzyme-based process to decompose it into pure monomers in a sustainable way;
• Repolymerization of the recycled monomers into like new plastic;
• Fabrication and quality verification of the new products made of recycled plastic materials

 
WhiteCycle has a global budget of nearly 9.6 million euros and receives European funding in the amount of nearly 7.1 million euros. The consortium’s partners are based in five countries (France, Spain, Germany, Norway and Turkey). Coordinated by Michelin, it has an effective governance system involving a steering committee, an advisory board and a technical support committee.

The partnership will aim at eliminating hazardous Potassium Permanganate Spray and most manual processes in denim finishing, while reducing Greenhouse Gas emissions, water and chemical use in the process

Hong Kong based Epic Group, a leading garment manufacturer for global brands today announced its strategic partnership with CleanKore, a denim innovation and patent licensing company. This partnership aims at scaling the CleanKore patented yarn dyeing technology that provides numerous sustainability benefits for both the denim mill and garment manufacturer.

CleanKore patented technology changes the chemistry and the process used to dyeing yarns at the denim mills by keeping intact the white core of the yarn and only dyeing the surface. This technology significantly reduces water, chemicals and process time in the denim garment finishing stage.

Denim garment finishing often involves onerous manual processes such as handsanding and hand whiskering, spraying of harmful Potassium Permanganate (PP) (done by heavily protective equipment donned personnel), and multiple washing cycles. CleanKore technology coupled with lasers enable elimination of the PP spray process, significantly improving health and wellbeing of apparel workers, as well as emissions of harmful chemicals. Manual processes are eliminated in most styles and significantly reduced in others.

CleanKore technology also enables the reduction of wash cycles – reducing water, chemical use and process time, adding to the sustainability credentials of the end products. The products currently tested by Epic Group and CleanKore demonstrate up to 44% of water savings in garment finishing and up to 60% of energy savings in the fabric dyeing stage, along with the elimination of PP spray.

Through their partnership, Epic Group and CleanKore are planning to rapidly scale up the adoption of this technology in partnership with Epic Group’s customer base. In the first year, the partnership plans to reach over 4 million pairs of denim and working towards a scale of 15 - 20 million pairs of denim per annum in the next 3 years, converting a large portion of Epic Group’s denim production to CleanKore technology.

• Annual assembly of ACIMIT, the Association of Italian Textile Machinery Manufacturers

• Digitalization and Sustainability Key to Resiliency for Italian Textile Machinery Sector

The objective critical issues faced by Italy as a whole throughout the course of 2021, primarily dictated by a pandemic that upset any and all pre-existing equilibriums, have not slowed or halted the Italian textile machinery sector.

Indeed, data presented during the annual assembly of ACIMIT, the Association of Italian Textile Machinery Manufacturers, held on 1 July proved decidedly positive, showing that in 2021 the sector recovered significantly compared to 2020, to the point of returning to pre-Covid levels.

Specifically, Italian textile machinery production amounted to 2.388 billion euros (+35% over 2020 and + 5% over 2019), with total exports amounting to 2.031 billion euros (+37% over 2020 and +9% over 2019).

However, these results do not cancel the obstacles that companies are still facing. Looking to the near future, expectations are for a rather uncertain outlook, as underscored by ACIMIT President Alessandro Zucchi: “2022 remains a year replete with unknown factors, starting with the Russian-Ukrainian conflict, along with the persistence of the pandemic, which seriously risk delaying expected growth consolidation for businesses in the sector. Difficulties in finding raw materials and components negatively affect the completion and fulfilment of orders processed as far back as 2021. To boot, rising energy costs and inflationary trends affecting numerous commodities are depressing overall business confidence. So the outlook for the sector is not so good.”
As such, the two cornerstones through which ACIMIT aims to support the Italian textile machinery sector are digitilization and sustainability.

4.0: The textile machinery sector looks to the future
The road to digital transformation has already led numerous manufacturers to completely rethink their production processes, rendering them more efficient and l ess expensive. The digital world is moving ahead at a decisive rate in the textile machinery sector, where the buzzwords are increasingly, for instance, the Internet of Things connecting to a company’s ecosystem, machine learning algorithms applied to production, predictive maintenance, and the integrated cloud management of various production departments. It is no coincidence that ACIMIT has focused decisively on its Digital Ready project, through which Italian textile machinery that adopt a common set of data are certified, with the aim of facilitating integration with the operating systems of client companies (ERP, MES, CRM, etc.).

A green soul
Combining production efficiency and respect for the environment: a challenge ACIMIT has made its own and which it promotes among its members through the Sustainable Technologies project. Launched by the association as early as 2011, the project highlights the commitment of Italian textile machinery manufacturers in the area of sustainability. At the heart of the project is the Green Label, a form of certification specifically for Italian textile machinery which highlights its energy and environmental performance. An all-Italian seal of approval developed in collaboration with RINA, an international certification body.
The assembly held on 1 July provided an opportunity to take stock of the Sustainable Technologies project, more specifically, with the presentation of the Rina Consulting survey on the Green Label’s evolution and impact in recent years.

The results have confirmed the initiative’s extreme validity. The technological advances implemented by the association’s machinery producers participating in the project have effectively translated into benefits in terms of environmental impact (reduction of CO₂ equivalent emissions for machinery), as well as economic advantages for machinery users.

With reference to the year 2021, a total of 204,598 tons of CO₂ emissions avoided on an annual basis have been quantified, thanks to the implementation of improvements on machinery. This is a truly significant reduction which, for the sake of comparison, corresponds to the carbon dioxide emissions generated by 36,864 automobiles travelling an average of 35,000 km a year. In terms of energy savings, the use of green labeled textile machinery has provided excellent performances in allowing for a reduction of up to 84% in consumption.

A round table discussion on the Green Label’s primary purpose
The environmental and economic impact generated in production processes for Italian textile machinery through the use of Green Label technologies was the focus of the round table which concluded the ACIMIT assembly.

Moderated by Aurora Magni (professor of the Industrial Systems Sustainability course at the LIUC School of Engineering), the debate involved Gianluca Brenna (Lipomo Printing House administrator and Vice President of the Italian Fashion System for Welfare), Pietro Pin (Benetton Group consultant and President of UNI for the textile-clothing area), Giorgio Ravasio (Italy Country Manager for Vivienne Westwood), as well as ACIMIT President Alessandro Zucchi.

Called on to compare common factors in their experiences relating to environmental transition processes for their respective companies, the participants were unanimous: the future of Italian textile machinery can no longer ignore advanced technology developments capable of offering sustainable solutions with a low environmental impact while also reducing production costs. This philosophy has by now been consolidated, and has proven to lead directly to a circular economy outlook.

The upcoming ITMA 2023 exhibition
Lastly, a word on ITMA 2023, the most important international exhibition for textile machinery, to be held in Italy from 8 to 14 June 2023 at Fiera-Milano Rho. Marking the 19th edition of ITMA, this trade fair is an essential event for the entire industry worldwide, providing a global showcase for numerous innovative operational solutions on display. A marketplace that offers participants extraordinary business opportunities. The participation of Italian companies is managed by ACIMIT.

The electrolyser producer Enapter has set itself the goal of developing its entire production process to run without negative impacts on the environment. As an important step on this journey, it is building the Enapter Campus production facility, which will be powered entirely from renewable energy produced on-site and in the neighbouring Bioenergiepark. The site in in Saerbeck, North Rhine-Westphalia combines electrolyser production, an R&D building, administration and office space, as well as a cantine over 82,000 square metres. Now the company wants to investigate what other measures can be implemented to achieve its “Life Cycle Impact Zero” aspirations – together with researchers from Fraunhofer UMSICHT, the Wuppertal Institute and the Institute of Sustainable Nutrition (iSuN) of FH Münster.

With the Life Cycle Impact Zero project, started on April 15, 2022, the parties want to develop and apply an especially comprehensive and holistic approach to environmental assessment. This includes chemical manufacturing and electrolyser production, as well as matters like the use of energy and water resources, the generation of waste or the human factor in general. This is intended to cover all interactions between business and people. That includes, in particular, Enapter’s employees, but also people in upstream and downstream value chains, users of the technology or residents close to the production site. A concept for sustainable employee catering is also being developed.

The basis for all environmental assessment that will be carried out is ISO 14040. The recognised international standard divides the research into four phases: Aim and scope of the study, inventory analaysis, impact assessment, as well as interpretation. Sensitivity analyses and scenario techniques are also used as further methods.

On the basis of these analyses, the 18-month project should derive concrete measures to avoid negative environmental impacts completely, if possible, for example in production, employee mobility or in energy supply. Furthermore, it will examine whether these measures are transferable to Enapter’s other locations – such as in Italy. Following on from the project, the steps defined should be implemented by Enapter in the next phase. In the subsequent Phase 3, a renewed analysis is planned. This will determine if the technological innovations achieved by then in the production and use of Enapter’s electrolysers can enable additional ecological improvements.

The Life Cycle Impact Zero project is supported by the State of NRW.

On June 13, EREMA Group and Borealis invited representatives of the international plastics and recycling trade press to Upper Austria for a sneak preview of the technological developments and lighthouse projects that the companies will present at K 2022, the plastics industry's international meeting place. The venue for the pre-K event was EREMA Group headquarters in Ansfelden.

EREMA Group K 2022 preview
In Düsseldorf, the subsidiaries of the EREMA Group - which are EREMA, PURE LOOP, UMAC, 3S, KEYCYCLE and PLASMAC - will present their technological innovations, services and support together at a Group trade fair stand for the first time. Seven new recycling systems and components will be presented that enable large-scale plants with a production capacity of up to 6 t/h while setting a milestone in recyclate quality and process stability. This is made possible by technological innovations in the plasticizing unit that have been specially developed for high throughputs with low specific energy consumption, the new EREMA 406 laser filter with a 50 percent larger screening area, and new digital assistance systems that will be launched at K 2022 and made available on the BluPort® customer platform. These include, for example, the PredictOn app, which helps to anticipate and eliminate imminent malfunctions based on continuous measurement and evaluation of machine data.

New series of machines for new target groups
For customers looking for rapidly available recycling systems for simple applications, EREMA Group subsidiary UMAC has an innovation in store for K 2022. The company, which has so far specialised in refurbishing and trading in previously owned equipment, is expanding its business area and in Düsseldorf will launch READYMAC, a standardised, prefabricated recycling solution that can be produced from stock, based on proven EREMA TVE technology.

Finally, in the inhouse recycling segment, PURE LOOP and PLASMAC will round off the wide range of machines offered by the group of companies with their product portfolio.

Live recycling and lighthouse projects at the Circonomic Center
In the outdoor area of the K show, EREMA will bring plastics recycling to life with live demonstrations in conjunction with cooperation partners. Different waste streams are processed for this purpose. The wide variety of high-quality applications for recyclate will be showcased in the "products made of recyclate" exhibition, ranging from technical components to consumer goods and food packaging.

Borealis – accelerating the transition towards a more circular future
Borealis is committed to using their expertise and global reach to advance the circular economy of plastics. At the joint Pre-K 2022 kick-off on June 13, Borealis provided a preview of their integrated way of circular thinking and featured topics and activities at the K Fair 2022 in October. The preview covered new technologies and innovations including new packaging and infrastructure applications of the Bornewables™ portfolio of circular polyolefin products, manufactured with renewable feedstocks. New applications for Design for Recyclability, Re-Use, chemical recycling and advanced mechanical recycling were also on display.

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

• Biotransformation technology for nonwovens

Avgol^® has received the prestigious Innovation Award at the RIGHT Hygiene conference in recognition of its collaboration with Polymateria in development of pioneering biotransformation technology for nonwovens.
 
Biotransformation is a unique functionality wherein a conventional nonwoven fabric can be modified to react to certain triggers to then begin a cascade, and importantly a fundamental chemical transformation of the polymer resin into a wax that is readily degraded by natural bacteria, microbes and fungi normally found in the environment.
 
“The transformation is triggered through the combined effects of the natural elements of decay - air, moisture, heat and sunlight,” said Mr. Sanjay Bhayani, Director of India Operations with Avgol. “Once triggered, the material will transform into a low molecular weight wax structure leaving no microplastics or toxic residue behind. Moreover, if the product comprising the biotransformation technology is disposed of in the normal way and facilities are available, then it can be recycled by readily available means.”

“By bringing the Biotransformation technology to the various potential markets in India, we hope to offer a real-world solution to waste management,” he said. “We particularly hope to address aspects of the creation of fugitive waste and remove this from the environment without causing additional, and potentially more dangerous, problems.”
